Caladium plant named ‘UF-85-5’

ABSTRACT

A new and distinct cultivar of  Caladium  plant named ‘UF-85-5’ is disclosed. ‘UF-85-5’ is characterized by its fancy leaves with a white/green leaf face and red spots, and it has been demonstrated to sprout early, produce attractive pot plants when tubers are forced in containers, and it possess exceptional sunburn tolerance.

ACKNOWLEDGEMENT OF FEDERAL RESEARCH SUPPORT

This invention was made with government support under FLA-BRA-04162 awarded by the Cooperative State Research, Education, and Extension Service, USDA. The government has certain rights in the invention.

Latin name of the genus and species of the plant claimed: Caladium hortulanum.

Variety denomination: ‘UF-85-5’.

BACKGROUND OF THE INVENTION

Caladiums [Caladium hortulanum Birdsey, Araceae Juss.] are ornamental aroids valued for their bright colorful leaves. They are propagated through tubers and tuber divisions. Many existing commercial Caladium cultivars cannot produce tubers stably or adequately for profitable commercial production. In other cases, sunburn tolerance or pot performance may not be satisfactory for commercial acceptance.

‘UF-85-5’ originated from a planned cross between ‘UF-607’ (female parent) and ‘Florida Fantasy’ (male parent) that was made in 2000. ‘UF-607’ was chosen from progeny of ‘Aaron’ and a breeding line, UF-FCT, that resulted from a cross between ‘Fire Chief’ and ‘Torchy’. ‘UF-607’ was released as ‘Summer Rose’ in 2005 (Deng and Harbaugh, HortScience, 41:468-470, 2006, U.S. Plant Pat. No. 20,446). ‘Florida Fantasy’ (unpatented) was a progeny of a cross between ‘Candidum Junior’ and ‘Red Frill’ (Wilfret, Univ. Fla., Inst. Food Agric. Sci., Circular, S-381, Gainesville, Fla., 1991). The ancestry of ‘Aaron’, ‘Candidum Junior’, ‘Fire Chief’, ‘Red Frill’, and ‘Torchy’ is unknown. ‘UF-85-5’ was selected in 2001. Asexual propagation by tubers and tuber division, and evaluations in field and pot studies in Bradenton, Fla. between 2002 and 2005 and in Wimauma, Fla. since 2005 have shown that the unique features of ‘UF-85-5’ are stable and ‘UF-85-5’ reproduces true to type in successive generations of asexual propagation.

Plant Breeder's Rights for this cultivar have not been applied for. ‘UF-85-5’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

‘UF-85-5’ is a fancy-leaved Caladium uniquely characterized with a white/green leaf face and red spots.

Compared to female parent ‘UF-607’ (‘Summer Rose’, U.S. Plant Pat. No. 20,446), the leaves of ‘UF-85-5’ are green-veined, while the leaves of ‘UF-607’ are pink/red-veined. In addition, the leaves of ‘UF-85-5’ express a primarily white/green face and are spotted, while leaves of ‘UF-607’ (‘Summer Rose’) express a primarily pink face and are non-spotted.

Compared to male parent ‘Florida Fantasy’ (unpatented), leaves of ‘UF-85-5’ are green-veined and spotted, while leaves of ‘Florida Fantasy’ are red-veined and non-spotted.

Plants of the new Caladium can also be compared to plants of the cultivar ‘Marie Moir’ (unpatented). In side-by-side comparisons conducted in the greenhouse in Wimauma, Fla., plants of ‘UF-85-5’ differ primarily from plants of ‘Marie Moir’ in leaf development and petiole color. Plants of ‘UF-85-5’ produce at least twice as many leaves as plants of ‘Marie Moir’ when grown in containers or in ground beds (Tables 2 and 3). Leaf petioles of ‘UF-85-5’ are green, whereas leaf petioles of ‘Maire Moir’ are darker brown.

Plants of ‘UF-85-5’ can also be compared to plants of the cultivar ‘Cranberry Star’ Caladium (U.S. Plant Pat. No. 20,792) in leaf color, color of spots, and sunburn tolerance. In side-by-side comparisons, plants of ‘UF-85-5’ express a white/green leaf face, red spots, and, excellent sunburn tolerance, while plants of ‘Cranberry Star’ express a more pure-white leaf face with fewer green veins, burgundy to purple spots, and susceptibility to sunburn.

BRIEF DESCRIPTION OF THE DRAWINGS

‘UF-85-5’ has not been observed under all possible environmental conditions. Its phenotype may vary somewhat with variations in the environment such as light intensity and temperature, without, however, any variance in genotype. The accompanying photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1986 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in 20.3-cm containers in Wimauma, Fla. during the summer in a polypropylene-covered shadehouse, and plants grown in ground beds in Wimauma, Fla. during the late summer in an outdoor nursery. All plants were grown under conditions and practices which approximate those generally used in commercial Caladium production.

During the production of the plants, day temperatures ranged from about 23.8-34.4° C., night temperatures ranged from about 20.5-23.8° C., and light levels were about 944 (shadehouse) or 9744 foot-candles (outdoor nursery). Plants grown in the shadehouse were about eight weeks from planting tubers when the photographs and detailed description were taken. Plants grown in the outdoor nursery were about fourteen weeks from planting tuber pieces when the photographs and detailed description were taken.

‘UF-85-5’ was evaluated for tuber production and plant performance under field conditions in Wimauma, Fla. in 2005 and 2006. The soil was an EauGallie fine sand with about 1% organic matter and a pH of 6.2. Plants were grown in a plastic-mulched raised-bed system maintaining a constant water table with seepage irrigation (Geraldson et al., Proc. Soil and Crop Sci. Soc. Fla. 25:18-24, 1965). In 2005, ground beds were fumigated on February 25 (6 weeks before planting), with a mixture of 67% methyl bromide and 33% chloropicrin (by volume) at the rate of 392 kg·ha⁻¹, and in 2006, the beds were fumigated on March 10, 10 days before planting, with the same fumigant mixture, but at the rate of 196 kg·ha⁻¹. Ground beds were 91 cm wide and 20 cm high. Caladium seed pieces (cut tuber propagules, about 2.5 cm) were planted 15 cm apart in three rows. Osmocote 18N-2.6P-10K 8-9 month controlled release fertilizer (Scotts Co., Marysville, Ohio) was applied to the bed surface when shoot tips emerged from the soil with nitrogen at 336 kg·ha⁻¹.

Field plots were organized in three randomized complete blocks, and each plot was 1.25 m² with 30 plants. In 2005, seed tuber pieces were planted in April and tubers were harvested in November; in 2006, seed pieces were planted in April and tubers were harvested in December. Each year, dried tubers were weighed and counted per plot, and then graded by maximum diameter: No. 2 (2.5-3.8 cm), No. 1 (3.8-6.4 cm), Jumbo (6.4-8.9 cm), Mammoth (8.9-11.4 cm), and Super Mammoth (>11.4 cm). The production index, an indicator of economic value of the harvested tubers, was calculated as: N (No. 2)+2N (No. 1)+4N (Jumbo)+6N (Mammoth)+8N (Super Mammoth); where N=number of tubers in each grade. An analysis of variance was conducted using the GLM procedure in the SAS program (SAS Institute, 2009) to compare the performance of ‘UF-85-5’ to that of ‘Candidum’, ‘Marie Moir’, and ‘Miss Muffet’. ‘Candidum’ was used for comparison, as it has been the No. 1 or 2 best-selling cultivar (Bell et al., Proc. Fla. State Hort. Soc. 111:32-34, 1998; Deng et al., Univ. Fla., Inst. Food Agric. Sci., EDIS Publication #ENH1007, Gainesville, Fla., 2008) and shares a similar coloration pattern to ‘UF-85-5’, except for not having colored spots on the leaf blades. ‘Marie Moir’ was the closest to ‘UF-85-5’ in leaf coloration among commercial cultivars. ‘Miss Muffet’ was used because it is a dwarf spotted-leaf cultivar.

‘UF-85-5’ was significantly more productive than ‘Candidum’ and ‘Miss Muffet’ in both the 2005 and 2006 growing seasons. Its average tuber weight was 115% (2005) and 83% (2006) greater than ‘Candidum’ and 75% (2005) and 103% (2006) greater than ‘Miss Muffet’; its production index was 66% (2005) and 53% (2006) higher than ‘Candidum’ and 49% (2005) and 65% (2006) higher than ‘Miss Muffet’; and its number of marketable tubers was 50% (2005) and 44% (2006) larger than ‘Candidum’ and 36% (2005) and 28% (2006) larger than ‘Miss Muffet’ (Table 1). ‘UF-85-5’ had consistent tuber weight, number of marketable tubers, and production index from 2005 to 2006, while ‘Marie Moir’ had poor consistency between growing seasons in tuber production. ‘Marie Moir’ yielded similarly well compared to ‘UF-85-5’ in 2005, but yielded poorly compared to ‘UF-85-5’ in 2006—approximately 33% less than ‘UF-85-5’s tuber weight and production index, and only about 50% of ‘UF-85-5’s number of marketable tubers.

Tuber distribution data (%) were transformed using the formula arcsine [square root (percentage/100)] before analysis of variance and mean separation. ^(y)The production index is an indicator of economic value of the crop harvested and is calculated as: N (No. 2) + 2N (No. 1) + 4N (Jumbo) + 6N (Mammoth) + 8N (Super Mammoth), where N = number of tubers in each grade.

Landscape performance of cultivars grown under full-sun conditions was evaluated in 2005 and 2006 under the same conditions used for evaluating tuber production. ‘Cranberry Star’ was also included with ‘Candidum’, ‘Marie Moir’, and ‘Miss Muffet’ for comparison to ‘UF-85-5’ in this test. The overall plant performance was rated multiple times (June, July, and August) in each growing season, on a scale of 1 to 5, with 1 being very poor (few leaves and lack of vigor), and 5 being excellent (full plants, numerous leaves, and bright color display). Similarly, leaf sunburn tolerance was also evaluated multiple times in each growing season on a scale of 1 to 5, with 1 being very susceptible to sunburns and showing numerous sun-damaged areas or holes on leaves and 5 being resistant to sunburns and not showing any sun-damaged areas. Approximately 4 months after planting, plant height, number of leaves, and foliar characteristics were measured.

Plants of ‘UF-85-5’ and ‘Cranberry Star’ were 9-13 cm taller and developed significantly more (˜100%) leaves than ‘Candidum’ and ‘Marie Moir’ (Table 2). Leaf sizes were similar among all cultivars tested, except for ‘Miss Muffet’, a known dwarf cultivar that was about half the size of other cultivars. ‘UF-85-5’ plants performed well in the landscape, with performance ratings between 3.6 and 4.8, similar to ‘Cranberry Star’, but significantly higher than those of ‘Candidum’ (1.7-3.1), ‘Marie Moir’ (1.4-3.3) and ‘Miss Muffet’ (1.5-2.4). ‘UF-85-5’ received the highest sunburn tolerance ratings in all the evaluations in each growing season, indicating better or significantly better sun tolerance in this cultivar in comparison to ‘Candidum’, ‘Marie Moir’, and ‘Miss Muffet’, and potential for use in sunny locations in the landscape. While ‘UF-85-5’ showed a high level of similarity to ‘Cranberry Star’, a recent release, in plant height, leaf number and leaf size, ‘Cranberry Star’ was very susceptible to leaf damage in full sun and thus limited to use in shady locations.

The suitability for container forcing was evaluated by forcing tubers in 11.4-cm containers. No. 1 tubers of ‘UF-85-5’, ‘Cranberry Star’, ‘Marie Moir’, and ‘Miss Muffet’ were planted either intact or de-eyed in a peat/vermiculite mix (VerGro Container Mix A, Verlite, Tampa, Fla.) on Mar. 26, 2007. The study was conducted in a greenhouse with 45% light exclusion during the summer in Wimauma, Fla. Average daily temperatures ranged from a low of 16° C. at night to 29° C. during the day throughout the experiment. Potted plants were arranged on metal benches in the greenhouse in 10 randomized complete blocks. Plant height, number of leaves, and foliar characteristics were recorded 8 weeks after planting.

‘UF-85-5’ sprouted in 30 days (intact) or 32 days (de-eyed) after planting, similar to ‘Miss Muffet’ and ‘Cranberry Star’, but 4-9 days earlier than ‘Marie Moir’ (Table 3). Container-grown ‘UF-85-5’ was 19-22 cm tall regardless of tuber treatment (intact or de-eyed), similar to ‘Marie Moir’ and ‘Cranberry Star’, but significantly taller (5-8 cm) than ‘Miss Muffet’. ‘UF-85-5’ produced 12 leaves on intact plants 8 weeks after planting and 21 leaves on de-eyed plants, similar to ‘Miss Muffet’, but significantly more than ‘Marie Moir’ or ‘Cranberry Star’. Leaves of ‘UF-85-5’ were significantly smaller than those of ‘Marie Moir’, especially when tubers were planted intact: ˜8 cm shorter and ˜6 cm narrower. When tubers were de-eyed, leaf size differences became smaller and might be still significant. With numerous medium-sized leaves, ‘UF-85-5’ produced pot plants of much higher quality ratings (3.4-4.4) than ‘Marie Moir’ (1.9-2.4), and similar to ‘Cranberry Star’ and ‘Miss Muffet’, which are known for their superior pot habits. Tuber de-eyeing improved the plant quality of ‘UF-85-5’.
